SWITCH-POINT SHIFTER.

SPECIFICATION forming part of Letters Patent N 0. 764,867, dated July12, 1904.

Application filed ApriLZ, 1904:. Serial No. 201,343. (No model.)

To all whom, it may concern:

Be it known that I, ROBERT HARRY ROB- ER'IS, a citizen of the UnitedStates, residing at San Antonio, in the county of Bexar and State ofTexas, have invented certain new and useful Improvements in Switch-PointShifters; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to devices for shifting the points of railroads;and it consists in the novel construction and combination of the partshereinafter fully described and claimed, whereby the points may beoperated from the car.

In the drawings, Figure 1 is a side view of the end portion of a car,showing the pointshifting mechanism. Fig. 2 is a plan view of the same.

A is the end portion of a street-car of any approved construction".

B is the point of a switch such as commonly used onstreet-railroads.

C is a bracket or frame which is secured to the end portion of thecar-frame. D is an operating-rod which is supported by the said bracketand provided with a blade d at its lower end. The blade has a taperededge d at its bottom for engaging with the point. The bracket has a hole6 in its lower part, in which the rod can move freely in all directions.

G is a spiral spring which encircles the rod D and which has its upperend rigidly secured to the rod. The lower end g of the spring is securedto the bracket near the hole a. The

rod D projects through this slot.

end of the rod D is provided with an operating-handle 1', which ispreferably arranged in line with the blade. The spring normally supportsthe blade, and the device is operated by the motorman, who depresses therod into engagement with the switch-point and shifts the point by adextrous manipulation of the blade without getting down from the car.

What I claim is 1. In a switch-point shifter, the combination, with abracket rigidlysecured to the car, of a depressible operating-rodmounted in the said bracket and provided with a shifting device at itslower end for engaging with the point, and a spiral spring encirclingthe said ro d, one end of the said spring being secured to the saidbracket and the other end to the said rod, said spring operating toraise the rod and permitting it to be moved axially and laterally.

2. In a switch-point shifter, the combination, with a bracket rigidlysecured to the car and provided with a lower part having a hole and anupper part having a slot arranged crosswise of the point, of adepressible operating-rod arranged loosely in the said hole and slot andprovided with a shifting device at its lower end for engaging with thepoint, and a spring secured to the said lower part of the bracket and tothe said rod above the said lower part, said spring operating to raisethe rod and permitting it to be moved axially and laterally.

In testimony whereof I have affixed my signature in the presence of twowitnesses.

ROBERT HARRY ROBERTS.
